Injection of the Hip With Hyaluronic Acid Under Distraction Plus Neurectomy of the Femoral and Obturator Nerve.

The hip is the location for many disorders, such as osteoarthritis, femoroacetabular impingement syndrome, avascular necrosis of the hip, and cartilage injuries, all of which cause chronic pain, disability, and limitation. It is estimated that 10% of the population ≥40 years of age will present with hip pain. The line of treatment goes from nonsteroidal anti-inflammatory drugs, physical therapy, lifestyle modification, intra-articular injections, and hip surgery. This will depend on the pathology, age, lifestyle, and sport activity of each patient. Currently, hip joint intra-articular injections represent a viable option for those patients who are not candidates for surgery or simply those who do not want surgery. Among the controversial indications for a hip injection is moderate-to-severe arthritis (grades III and IV). Hip injections are considered a diagnostic and therapeutic procedure, with a sensitivity of 87% and specificity of 100% reported, and will differentiate between an intra-articular pathology versus an extra-articular pathology and a neuropathic pain arising from the lumbar spine. Radiofrequency nerve ablation or neurectomy of the femoral and obturator nerve has been implemented more frequently not only for patients with mild-to-moderate osteoarthritis but also in those who present with femoroacetabular impingement syndrome and cartilage lesions who do not wish to undergo surgery.

Hip Arthroscopy in Adolescents Through an Extra-Capsular Approach.

Hip arthroscopic treatment for femoroacetabular impingement syndrome and labral tears is the gold standard in the adult and adolescent population, as we all know the most common surgical approach to the hip is entering the central compartment with fluoroscopy and with continuous distraction. A periportal capsulotomy in traction must be done to have visibility and instrument maneuverability. These maneuvers avoid scuffing the femoral head cartilage. In adolescents, extreme care must be taken in hip distraction, as the force used can cause iatrogenic neurovascular lesions, avascular necrosis, and lacerations of the genitals and foot/ankle. Experienced surgeons around the world have developed an extracapsular approach to the hip with smaller capsulotomies with a low complication rate. This approach to the hip has brought attention in the adolescent population because it is more secure and simple. Less force of distraction is needed because the capsulotomy is done first. This surgical technique allows observation of the cam morphology while entering to the hip without distraction. We describe an extracapsular approach as an option to treat femoral acetabular impingement syndrome and labral tears in the pediatric and adolescent population.

The Yoga Mat Technique in Postless Hip Arthroscopy.

Hip arthroscopy for the treatment of femoroacetabular impingement syndrome with anti-sliding techniques and without the use of a perineal post to achieve hip distraction has increased greatly in the past 5 to 10 years. To access the hip joint, distraction is mandatory to treat intra-articular disorders such as labral tears, acetabular cartilage defects, loose bodies, ligamentum teres tears, and avascular necrosis of the hip. In hip distraction, counter-distraction is needed, and this is achieved with a bulky and cushioned perineal post. Most of the described techniques in hip arthroscopy worldwide use a perineal post, but iatrogenic pudendal nerve, genital lacerations, hematomas, and groin complications have been reported to occur. In Latin American countries, disposable hip pad devices are expensive, and not all the arthroscopic companies provide them. Our yoga mat technique provides enough countertraction to achieve adequate hip distraction. Labral repair, labral reconstruction, and decompression of femoroacetabular impingement syndrome have been achieved properly, reliably, and reproducibly, and no Trendelenburg position is needed. Postless hip arthroscopy is made simple, and positioning the patient is not difficult. Hip surgeons can adapt this technique to a fracture table, a hip distractor, and a standard operating room table.

Hip Arthroscopy and Core Decompression for Avascular Necrosis of the Femoral Head Using a Specific Aiming Guide: A Step-by-Step Surgical Technique.

Avascular necrosis of the femoral (AVN) head is a disabling disease that affects function, mobility, and quality of life in the young adult. Its pathology involves blood circulation disruption of the femoral head and subchondral infarction. This leads to cartilage thinning, femoral head depression, and cartilage breakage, which results in hip osteoarthritis. In the past decade the prevalence of intraarticular pathology has been almost 95%, this revealed with hip arthroscopy (HA). HA and core decompression (CD) of the femoral head can be used effectively and concomitantly to treat AVN with excellent results, HA allows for excellent visualization of the hip joint cartilage, allowing treatment of femoroacetabular impingement syndrome (FAIS) and intra-articular pathology. Our technique demonstrates that retrograde core decompression with allograft and mixed bone matrix is an excellent choice of treatment in the early stages of AVN/ONFH. The femoral head-specific aiming guide is very reliable, is simple to use arthroscopically if placed in the posterolateral portal of the hip, and offers exact pin placement at the necrotic site, as well as less operative time and less radiation to the patient and surgical team.

The Outside-In Technique for Slipped Capital Femoral Epiphysis: A Safe and Reproducible Approach in Hip Arthroscopy.

Femoroacetabular impingement syndrome caused by slipped capital femoral epiphysis (SCFE) can be successfully treated arthroscopically and with the minimally invasive, outside-in surgical technique. The advantages of the technique are that the residual cam-type deformity caused by the slippage can be corrected and reconstructed reliably and reproducibly before distracting the hip joint; and radiation with fluoroscopy is used for only definitive reduction and reconstruction, which is obtained with cannulated screws. In addition, this safe technique allows distraction of the hip after screw placement, without affecting the reconstruction, to address labral tears and chondrolabral delaminations caused by the impingement.
